AH... Ok. I just didn't want a beginner to go ahead and drill a hole at 3/8" and try to thread it with a 1/4" 20 tap, ya know?

As far as rubber bands are concerned, well, I tried to make my point. I won't argue about it (not that one was intended here). I think it's prudent to throw them away after the day's flying. At $2.99 for a quarter pound, they are cheap enough to replace. And, considering what would happen if they broke in flight due to a hard UP elevator input, or a high G turn, even if both were done by mistake, well, it really doesn't matter what the cause was, if they break under stress like that, and the wing comes off, you will quickly learn the meaning of "lawn dart".
